            <<~EOS
              The installation of the Homebrew package takes place in an isolated environment, so ensure JJava visibility by running:
                echo 'export JUPYTER_PATH="#{kernel_path}:$JUPYTER_PATH"' >> ~/.zshrc; source ~/.zshrc (macOS)
                echo 'export JUPYTER_PATH="#{kernel_path}:$JUPYTER_PATH"' >> ~/.bashrc; source ~/.bashrc (Linux)
              Although JJava doesn't depend on java, it requires jre>=11 to run.
              Make sure you have one in your PATH.
